Robert Lee Hayes, nicknamed "Bullet Bob", was an American sprinter and professional football player. After winning gold medals at the 1964 Summer Olympics, he played as a split end in the National Football League (NFL) for the Dallas Cowboys. Hayes is the only athlete to win both an Olympic gold medal and a Super Bowl ring. He was a two-sport standout in college in both track and field and football at Florida A&M University. Hayes was enshrined in the Dallas Cowboys Ring of Honor in 2001 and was selected for induction in the Pro Football Hall of Fame in January 2009. Hayes is the second Olympic gold medalist to be inducted to the Pro Football Hall of Fame, after Jim Thorpe. He once held the world record for the 70-yard dash. He also is tied for the world's second-fastest time in the 60-yard dash. He was once considered the "world's fastest human" by virtue of his multiple world records in the 60-yard, 100-yard, 220-yard, and Olympic 100-meter dashes. He was inducted into the United States Olympic Hall of Fame.

The 1964 Summer Olympics , officially the Games of the XVIII Olympiad and commonly known as Tokyo 1964, were an international multi-sport event held from 10 to 24 October 1964 in Tokyo, Japan. Tokyo had been awarded the organization of the 1940 Summer Olympics, but this honor was subsequently passed to Helsinki due to Japan's invasion of China, before ultimately being cancelled due to World War II. Tokyo was chosen as the host city during the 55th IOC Session in West Germany on 26 May 1959.
